Two days later, that is, on 21 February, the missile seeker program was successfully rewritten, so Lin Yuan asked Ma Zhiliang's engineers to carry equipment to the fleet's warships to modify the missiles, and in the early morning of 22 February, half of the missiles on the ship had been refitted, and the Japanese troops, who knew nothing about this matter, were also heading towards the sea area where Lin Yuan's troops were located.

While four battleships and four battlecruisers were moving forward, the three surviving Fukiyuki-class destroyers also set off for Chidorijima, and the cruising range of the Fukiyuki-class destroyers was relatively poor, with a cruising range of less than 2,000 nautical miles at a speed of 18 knots, which was still under improved conditions, while in Lin Yuan's time, the cruising range of this type of destroyer at a speed of 18 knots was only about 1,000 nautical miles.

This was because the oil tanks of the Fuxue-class destroyers were designed to be relatively small, and in order to overcome this weakness, the Japanese army further reduced the weight of the hull, and since the purpose of this operation was to transport the marines to the island, there was no need to use torpedoes, so the Japanese dismantled all the torpedo tubes, along with the torpedo launch commander and other things, and all the officers and soldiers of the torpedo launch group were left on the shore.

At nine o'clock in the morning of 22 February, Heihachiro Togo sailed into the waters near Kiyojin with four Kongo-class battlecruisers, two Ise-class battleships, and two Fuso-class battleships, with Kongo in front and other ships behind.

Heihachiro Togo stood in the command room, looking at the sea through the porthole, and thought to himself: "Today's sky is relatively gloomy, and it is not easy to detect incoming missiles with the naked eye, I hope that the Americans' new radar warning device can work, if their radar warning does not work, then our eight warships, I am afraid, will become a delicacy on the plate of Lin Yuan's troops in an instant." ”

At this time, Heihachiro Togo turned his head to Anderson and said, "Mr. Anderson, can your alarm device distinguish whether the electromagnetic wave is emitted by radar or missile?" ”

Anderson nodded and said: "Yes, because the missile is moving at high speed all the time, the frequency of the electromagnetic wave emitted will change rapidly. ”

Heihachiro Togo nodded lightly, and at this moment, the radar on Lin Yuan's warship spotted the Japanese warship, and the radar chief reported to Yu Feng: "Report to the commander, we have discovered the Japanese fleet!" There were eight warships at a distance of 45 km, and the target course was 30 degrees north-east at a speed of 25 knots. ”

Yu Feng asked, "Have you judged any warships?" ”

The radar chief reported: "We are still accumulating data for interpretation, and in a minute we will be able to know the model of the warship." ”

Yu Feng said: "Okay, notify me as soon as you judge the type of enemy warship." A minute later, the radar chief reported to Yu Feng: "Report to the commander, we have read out the types of Japanese warships, which are Ise-class battleships, Fuso-class battleships, and Kongo-class battlecruisers. ”

After hearing the report, Yu Feng said excitedly: "Okay, great, the Japanese army can't stand the pressure of public opinion, so they take the initiative to attack and find our fleet to seek a capital ship showdown!" Order the missile department, get ready for launch. ”

The order was immediately transmitted to the missile department, and the missile department immediately began to prepare, and three minutes later, the chief officer of the missile department reported to Yu Feng: "The missile has been prepared, and the target data can be imported at any time." ”

Yu Feng said: "Okay! Then he ordered: "Radar room, transmit the data on the movement of the Japanese flagship to the missile department." ”

Soon the radar room sent back a message: "Data transfer complete. ”

Yu Feng said: "Attention to the missile department, launch a missile at the target warship!" ”

The officer of the missile department hurriedly asked: "Commander, do you launch only one missile?" ”

Yu Feng said: "Launch a missile first and see if our improvements can work." ”

The missile department then replied: "Understood! The sound of "missiles ready to launch, 10 seconds countdown to prepare" sounded on the ship, and after the 10-second countdown, the missiles whistled out and flew towards the Japanese flagship Ise in the fleet.

On the Ise, Anderson stared intently at the radar siren light, feeling conflicted, hoping that it would light up sooner to prove that their equipment was working, and that it would not light up and that no missiles were coming.

Anderson was conflicting, suddenly the indicator light of the radar alarm flashed like crazy, and at the same time, the buzzer also "ticked" non-stop, Anderson hurriedly said to the operator: "Is it a missile?" ”

The operator said: "Yes, the frequency changes very quickly, there must be a high-speed target approaching us, it must be a missile of Lin Yuan's troops!" ”

Anderson hurriedly said to Heihachiro Togo: "Togo-kun, please look, we have found a missile." ”

Heihachiro Togo hurriedly said, "Can you know how far away the missile is from us?" ”

Anderson shook his head lightly and said, "The radar alarm can't tell us how far away the missile is from us, but the radar alarm can sense the strength of the radar signal it receives, and the closer it is, the stronger the buzzer will be." ”

Heihachiro Togo nodded and said, "Start the jamming wire transmitter immediately!" The launcher on the side of the warship was immediately activated, throwing a large cloud of interference filaments into the sky, and Heihachiro Togo thought to himself, "Now is the time to retreat!" So Togo Heihachiro ordered: "All ships prepare, turn, and retreat at full speed!" ”

Before leaving, Togo Heihachiro had already informed the captains of the warships of the purpose of the battle, and they all understood Togo Heihachiro's combat intentions, so after the retreat order was issued, the Japanese warships began to turn and retreat.

As soon as the Japanese warship turned, the warship of Lin Yuan's troops was discovered through the radar, and Yu Feng decisively ordered: "The Japanese must not be allowed to escape, chase!" Lin Yuan's fleet then turned around and sailed in the direction of the Japanese retreat.

While the two fleets were turning, the missiles were still flying towards the Iseship, and Heihachiro Togo listened to the sound of the buzzer getting stronger and stronger, and couldn't help but feel a burst of panic in his heart, thinking: "We have improved the radar alarm, will Lin Yuan's troops also improve their weapons?" What if our jamming wires are not able to jam the missiles of the Lin Yuan fleet? ”

As the minutes ticked by, and the missiles got closer and closer, Heihachiro Togo ordered, "Put some jamming wires every once in a while!" Don't let the missiles take advantage of it! ”
